Domino liver transplantation for maple syrup urine disease in children: A single-center case series. Pediatr Transplant 2023; 27:e14603. [PMID: 37658594 DOI: 10.1111/petr.14603] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/02/2023] [Revised: 07/20/2023] [Accepted: 08/25/2023] [Indexed: 09/03/2023]
Abstract
BACKGROUND Domino liver transplant (DLT) represents another type of liver donor to expand the donor pool. Recent reports of successful DLT in children with maple syrup urine disease (MSUD) show promising long-term outcomes. METHODS It was a retrospective study. All children with MSUD were paired with either recipients with end-stage liver disease (ESLD) or non-MSUD metabolic disease. Each pair underwent simultaneous liver transplant (LT), where the MSUD recipient received the graft from a living-related donor and the liver explanted from the MSUD donor was transplanted to the respective paired domino recipient. We report our experience regarding the techniques and outcomes of DLT at our center. RESULTS Eleven children with MSUD and 12 respective DLT recipients were enrolled, one of which was domino split-liver transplantation. DLT recipients included seven ESLD, two propionic acidemia (PA), one glycogen storage disease(GSD) type-1, one GSD type-3, and one Citrullinemia. Post-LT ICU and hospital stays were comparable (p > .05). Patient and graft survival was 100% and 66.6% in the MSUD group and DLT recipients at a mean follow-up of 13.5 and 15 months. There was no death in the MSUD group as compared to four in the DLT group. The amino acid levels rapidly normalized after the LT in the children with MSUD and they tolerated the normal unrestricted diet. No vascular, biliary, or graft-related complications were seen in the post-transplant period. No occurrence of MSUD was noted in DLT recipients. CONCLUSION DLTs have excellent post-surgical outcomes. DLT should be strongly considered and adopted by transplant programs worldwide to circumvent organ shortage.

Technique and outcome of domino liver transplantation from patients with maple syrup urine disease: Expanding the donor pool for live donor liver transplantation. Clin Transplant 2019; 33:e13721. [PMID: 31556146 DOI: 10.1111/ctr.13721] [Citation(s) in RCA: 18] [Impact Index Per Article: 3.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/29/2019] [Revised: 08/22/2019] [Accepted: 08/31/2019] [Indexed: 01/26/2023]
Abstract
AIM/BACKGROUND Domino liver transplantation (DLT) using liver allografts from patients with metabolic disorders enhances organ utilization. Short- and long-term course and outcome of these patients can impact the decision to offer this procedure to patients, especially those with diseases that can potentially be cured with liver transplant. We reviewed the outcomes of DLT from maple syrup urine disease (MSUD) patients in our large academic pediatric and adult transplant program. METHODS All patients receiving DLT were analyzed retrospectively with a minimum of one-year follow-up period for patient and donor characteristics, early and late postoperative complications and patient and graft survival with their MSUD donors in terms of age, weight, MELD/PELD scores, cold ischemia time, postoperative leucine levels, and peak ALT (alanine aminotransferase) levels during the first 48 postoperative hours. RESULTS Between 2006 and May 2019, 21 patients underwent domino liver transplantation with live donor allografts from MSUD patients. Four patients transplanted for different metabolic diseases are focus of a separate report. Seventeen patients with minimum one-year follow-up period are reported herein. The indications were primary sclerosing cholangitis (PSC, n = 4), congenital hepatic fibrosis (CHF, n = 2), alpha-1 antitrypsin deficiency (A-1 ATD, n = 2), progressive familial intrahepatic cholestasis (PFIC, n = 2), cystic fibrosis (n = 1), primary biliary cirrhosis (PBC, n = 1), neonatal hepatitis (n = 1), embryonal sarcoma (n = 1), Caroli disease (n = 1), hepatocellular carcinoma (HCC, n = 1), and chronic rejection after liver transplantations for PSC (n = 1). All patients and grafts survived at median follow-up of 6.4 years (range 1.2-12.9 years). Median domino recipient age was 16.2 years (range 0.6-64.6 years) and median MSUD recipient age was 17.6 years (range 4.8-32.1 years). There were no vascular complications during the early postoperative period, one patient had portal vein thrombosis 3 years after DLT and a meso-Rex bypass was successfully performed. Small for size syndrome (SFSS) occurred in reduced left lobe DLT recipient and was managed successfully with conservative management. Biliary stricture developed in 2 patients and was resolved by stenting. Comparison between DLT and MSUD recipients' peak postoperative ALT results and PELD/MELD scores showed lower levels in DLT group (P-value <.05). CONCLUSIONS Patient and graft survival in DLT from MSUD donors was excellent at short- and long-term follow-up. Metabolic functions have been normal in all recipients on a normal unrestricted protein diet. Ischemia preservation injury based on peak ALT was significantly decreased in DLT recipients. Domino transplantation from pediatric and adult recipients with selected metabolic diseases should be increasingly considered as an excellent option and alternative to deceased donor transplantation, thereby expanding the living donor pool. This, to date, is the largest world experience in DLT utilizing livers from patients with MSUD.

Abstract
UNLABELLED Liver transplantation has been reported in patients with methylmalonic acidemia (MMA), but long-term outcome is controversial. Many patients with other approved indications for liver transplantation die before donor grafts are available. A 28-year-old man with MMA underwent cadaveric liver transplantation. His liver was used as a domino graft for a 61-year-old man with primary sclerosing cholangitis, who had low priority on the transplant waiting list. Surgical outcome was successful, and after transplantation both patients have excellent graft function. The patient with MMA showed substantial decrease in methylmalonate in urine (from 5,277 ± 1,968 preoperatively to 1,068 ± 384 mmol/mol creatinine) and plasma (from 445.9 ± 257.0 to 333.3 ± 117.7 μmol/l) over >1-year follow-up, while dietary protein intake increased from 0.6 to 1.36 ± 0.33 g/kg/day. The domino recipient maintained near-normal levels of plasma amino acids but did develop elevated methylmalonate in blood and urine while receiving an unrestricted diet (peak plasma methylmalonate 119 μmol/l and urine methylmalonate 84-209 mmol/mol creatinine, with 1.0-1.9 g/kg/day protein). Neither patient demonstrated any apparent symptoms of MMA or metabolic decompensation during the postoperative period or following discharge. CONCLUSION Liver transplantation substantially corrects methylmalonate metabolism in MMA and greatly attenuates the disease. In this single patient experience, a liver from a patient with MMA functioned well as domino graft although it did result in subclinical methylmalonic acidemia and aciduria in the recipient. Patients with MMA can be considered as domino liver donors for patients who might otherwise spend long times waiting for liver transplantation.

Abstract
Almost 100 mutations in the human transthyretin (TTR) gene cause the autosomal dominant disorders of familial amyloidotic polyneuropathy (FAP) and familial amyloidotic cardiomyopathy. While these have been clinically classified as separate disorders, the peripheral and autonomic nervous systems and the heart are frequently involved in the same patient. Deposition of amyloid derived from a kinetically or thermodynamically unstable mutant TTR precursor produces an ascending sensorimotor polyneuropathy with marked autonomic involvement. Since 1990, treatment has been liver transplantation from a donor carrying two wild-type TTR genes, providing a crude form of gene therapy. Multiple studies have shown that small molecules fitting in the T4-binding pocket of TTR can stabilize the molecule, reducing its capacity to release the fibril precursor. Tafamidis is the first molecule to be tested in a placebo-controlled trial in patients with TTR-associated FAP. While the trial did not achieve its primary endpoints, it did stabilize TTR in vivo and had a favorable effect on some aspects of disease progression, particularly when administered early in the course. It may represent an alternative to liver transplantation, particularly in patients with early disease related to the V30M mutation. Longer-term studies are required to determine whether it represents a stabilizing or remittive form of treatment.

Abstract
In many transplantation centers domino liver transplantation is an established procedure, increasing the number of available liver grafts. Increasingly, grafts from familial amyloidotic polyneuropathy (FAP) patients are used. Ocular involvement is a well known manifestation of FAP, and can be vision-threatening. The aim of this study was to evaluate the risk of development of familial amyloidotic polyneuropathy ocular manifestations in domino liver recipients. Forty-four cirrhotic patients submitted to liver transplantation were studied, with an average of 6 years of follow up after the procedure. Twenty two patients had received a liver from a FAP donor (Group 1) and 22 had received a liver from a non-FAP cadaveric donor (Group 2). Both groups were similar for mean age and gender. Routine ophthalmological examinations with particular attention to amyloid deposition in the anterior segment and vitreous, peripheral retina state, lacrimal functions tests (Schirmer and tear break-up time) and pupillometry (dynamic and static) were performed. No statistically significant differences were observed in all studied ophthalmic parameters between the two groups. No FAP related ophthalmic manifestations were detected after 6 years of domino liver transplantation, but further prospective regular ophthalmological examinations are necessary to detect the eventual development of late ocular manifestations.

Abstract
The long-term shortage of livers available for transplantation has spurred the development of many strategies to bolster the donor organ supply. One particularly innovative strategy is domino liver transplantation in which a select group of liver transplant recipients can donate their explanted native livers for use as liver grafts in other patients. Several hereditary metabolic diseases (such as familial amyloid polyneuropathy, maple syrup urine disease, and familial hypercholesterolemia) are caused by aberrant or deficient protein production in the liver, and these conditions can be cured with an orthotopic liver transplant. Although their native livers eventually caused severe systemic disease in these patients, these livers are otherwise structurally and functionally normal, and they have been used successfully in domino liver transplants for the past 15 years. This article will review the indications for donating or receiving a domino liver transplant, the surgical techniques necessary to perform these transplants, as well as the recently revealed long-term outcomes and risks of domino transplantation.

Abstract
Although domino liver transplantation (LT) is an established procedure, data about the operative risks are limited. This study aimed at evaluating the operative risks of domino LT. Two retrospective analyses were conducted (comparison of familial amyloid polyneuropathy [FAP] liver donors [61 patients] vs. FAP nondonors [39 patients] and FAP liver recipients [61 patients] vs. deceased donor liver recipients [61 patients]). First analysis showed a 60-day mortality of 6.6% for FAP donors and 7.7% for FAP nondonors (p = 1.0). No patient developed primary graft nonfunction. Acute rejection was higher in FAP nondonors compared to FAP donors (38.5% vs. 13.1%). Both groups had similar vascular and biliary complication rates. ICU stay was similar, whereas total hospitalization was longer for FAP nondonors. Both groups had similar 1- and 5-year patient and graft survival rates (83.4% vs. 87.2%, and 79.8% vs. 71.8%, p = 0.7) and (83.3% vs. 87.2%, and 79.1% vs.71.8%, p = 0.7). The second analysis showed a 1.6% mortality for FAP liver recipients vs. 3.2% of the control group (p = 1). Both groups had similar morbidity and technical complication rates (18.0% vs. 13.1%, p = 0.45) and (0.18 vs. 0.15, p = 0.65). The domino procedure does not add any risk to FAP donor or recipient. It increases the organ pool allowing transplantation of marginal recipients who otherwise are denied deceased donor liver transplantation.

Abstract
Domino liver transplantation (DLT) using grafts from patients with familial amyloidotic polyneuropathy (FAP) is an established procedure at many transplantation centers. However, data evaluating the long-term outcome of DLT are limited. The aim of the present study was to analyze the risk of de novo polyneuropathy, possibly because of amyloidosis, and the patient survival after DLT. At our department, 28 DLT using FAP grafts were conducted between January 1997 and December 2005. One patient was twice subjected to DLT. Postoperative neurological monitoring of peripheral nerve function was performed with electroneurography (ENeG) in 20 cases. An ENeG index based on 12 parameters was calculated and correlated to age and/or height. Three patients developed ENeG signs of polyneuropathy 2-5 years after the DLT, but with no clinical symptoms. The 1-, 3- and 5-year actuarial patient survival in hepatocellular carcinoma (HCC) patients (n = 12) and non-HCC patients (n = 15) was 67%, 15%, 15% and 93%, 93%, 80%, respectively (P = 0.001). Development of impaired nerve conduction in a proportion of patients may indicate that de novo amyloidosis occurs earlier than previously expected. Survival after DLT was excellent except in patients with advanced HCC.

Abstract
BACKGROUND Recently, sequential liver transplantation has been performed with an explanted liver from a patient with familial amyloidotic polyneuropathy (FAP) because of the shortage of donors. However, metabolism of amyloidogenic transthyretin (ATTR), the pathogenic protein of FAP, has not been well studied in patients who have undergone sequential liver transplantation. The purpose of this study was to examine the changes in serum ATTR levels and to investigate the presence of an autoantibody in patients who underwent sequential liver transplantation with an explanted organ from a patient with heterozygotic FAP (FAP ATTR Val30Met). METHODS This was a case study performed at the Kumamoto University School of Medicine, Kumamoto, Japan, and Kyoto University School of Medicine, Kyoto, Japan. Intervention occurred by sequential liver transplantation with an explanted FAP patient's liver. Levels of normal TTR and ATTR in the two patients who received the transplanted liver were analyzed by means of an enzyme-linked immunosorbent assay (ELISA) and a matrix-assisted laser desorption/time-of-flight mass spectrometry. In addition, the presence of an autoantibody against ATTR Val30Met was evaluated via ELISA using purified ATTR Val30Met from homozygotic FAP patients' sera. RESULTS After the operation, the variant TTR levels were unexpectedly lower than levels of normal TTR in serum samples from patients with a transplanted liver from the FAP patient. An autoantibody against the variant TTR was detected on day 3 after the operation in the serum of those patients and continued to be present for at least 2 months after the operation. CONCLUSIONS An autoantibody against the variant TTR may reduce the serum levels of variant TTR. Although the antibody may play a beneficial role in reducing the pathogenic protein, the long-term effect of the antibody must be investigated further.

Abstract
BACKGROUND Domino or sequential liver transplantation (DTXL) is a kind of living donor transplant, which was proposed in 1993 and performed for the first time in 1995; later on, more than 45 have been reported. The liver from a patient with familial amyloidotic polyneuropathy(FAP) is used to another patient aged more than 60 with hepatic disease generally cancer, because FAP livers are anatomically and functionally normal except for the synthesis of the systemic TTR variant which only could generate FAP in the recipient after more than 8 years. PATIENTS AND METHOD The three first cases of DTXL performed in Spain are presented. The donors were FAPTTRMet30 patients from the Major can focus. The first recipient showed severe hyperinsulinism due to metastatic liver from malignant insulinoma; the others had hepatocellular carcinoma on a cirrhotic liver. RESULTS During the post operatory period liver function of recipients was perfect,and hyperinsulinism disappeared in the first; this patient died after 10 days by sepsis whereas the others showed normal liver function, no recurrent cancer nor onset of FAP. The donors outcome was normal with perfect liver function. CONCLUSIONS Based on our results, in agreement with previous reports, we conclude that DTXH is valid procedure for a selected patient group. In addition they increase the pool of liver donors and therefore diminish the overloaded waiting lists.

Abstract
The advantages and disadvantages of using monoethylglycinexylidide (MEGX), the major metabolite of lidocaine, as a probe of hepatic function in liver transplantation are reviewed. A 'real time' test of liver function should give a measure of current hepatocellular capacity rather than reflect past damage. The hepatic metabolism of lidocaine to MEGX is the basis of a flow-dependent dynamic test of liver function. In pre-transplantation patients, data from this MEGX test support its role in assessing the risk of morbidity and mortality. In assessing the liver transplant donor, there are differences concerning its apparent usefulness and these must be resolved. In the liver transplant recipient, this MEGX test is also useful for measuring real-time hepatic metabolizing activity, and low MEGX values reflect the clinical condition of the patient. At present, however, this test has several limitations. Therefore, a comprehensive evaluation, not only by the MEGX test but also by a combination of other conventional liver function tests (biochemical parameters, etc.), or with histological evaluation, is thought to be desirable for deciding whether a liver transplantation should be carried out or not.

Abstract
BACKGROUND Although domino liver transplantations (OLT) from cadaveric donors have been performed in about 50 cases since 1995, only one case in the Japanese literature has been reported on a domino OLT from a living related donor. The difficulties of the later surgery lie in the small size of the graft volume and the short length of the vascular cuffs in the graft. METHODS The left lobe graft was procured from a 43-year-old younger brother of a familial amyloidotic polyneuropathy (FAP) patient. Next, the left lobe graft (510 g, 44% of the estimated standard liver volume of the FAP patient) was implanted into the 48-year-old female FAP patient. At surgery for the FAP patient, a sufficient length of the vascular cuffs was secured by an extended left lobe resection, although the right lobe graft was able to maintain sufficient vascular cuffs. The right lobe graft (720 g, 54% of the recipient's estimated standard liver volume) was then implanted in the 43-year-old male patient with liver cirrhosis and hepatocellular carcinoma (stage IV-A). RESULTS The two recipients were discharged from the hospital 1 month after OLT. At 7 months after OLT, they are both doing well and the domino recipient is free of any tumor recurrence. CONCLUSION A domino OLT from the living related donor can therefore be done safely when careful attention is paid to the graft volume and the length of the vascular cuffs for anastomosis.

Abstract
BACKGROUND Shortage of liver donors means that new methods of liver procurement must be explored. In domino transplantation, organs explanted during transplantation in one patient are transplanted into a second patient. Domino procedures can be performed with livers from patients having transplantation for hepatic metabolic disorders that cause systemic disease without affecting other liver functions. Familial amyloidotic polyneuropathy (FAP) type I is one of these. STUDY DESIGN We reviewed the Paul Brousse experience with a domino liver transplant program for FAP, hoping to extend the approach to other metabolic disorders. RESULTS Livers from 10 patients transplanted for FAP type 1 were used for domino transplants to patients with unresectable primary or metastatic liver cancers. There was no perioperative mortality. Neuropathy or cardiomyopathy did not increase the morbidity of the domino liver explant and transplant procedures. Morbidity for the domino recipients did not appear to be increased. Variant transthyretin was detected in the serum in FAP liver recipients, with no immediate clinical consequences. CONCLUSIONS The domino approach is feasible and requires careful planning of the surgical procedures for liver explantation, particularly for the nature and site of vascular anastomoses. Domino transplantation of metabolically dysfunctional livers creates new categories of potential donors and potential recipients. It raises new ethical, technical, and societal issues. The domino approach could be used in several genetic or biochemical disorders now treated by liver transplantation. It has the potential to increase the number of liver grafts available for transplantation.

Abstract
BACKGROUND/AIMS The primary cause of Familial Amyloidotic Polyneuropathy is a variant transthyretin gene on chromosome 18. Progressive polyneuropathy followed by fatal cardiac and renal failure commonly manifest during middle age. Within 10 years after onset of clinical symptoms, affected individuals usually die due to malnutrition or heart failure. Currently, liver transplantation is the only available therapeutic option. METHODS We performed liver transplantation in two patients with Familial Amyloidotic Polyneuropathy carrying the transthyretin-30 mutant. Two patients aged more than 50 years received the two explanted amyloidotic livers. This procedure is called Domino liver transplantation. We report the outcome in the studied subjects and analyze the metabolic consequences of this procedure. RESULTS We determined the serum half-life of transthyretin-30 as 2.25 days using daily monitoring of transthyretin-30 levels. An affected amyloidotic patient had an increased serum concentration of lipoprotein(a) of 78 mg/dl before transplantation. The tumor patient, who received the organ from this affected patient, developed an almost identical serum concentration of lipoprotein(a) after liver transplantation, confirming the liver as the primary site of synthesis of this lipoprotein. CONCLUSION Once Domino liver transplantation has been performed, the impact of the liver-dependent metabolism of specific proteins of interest can be studied.
